摘要
Abstract
Electronic Toll Collection(ETC) has been networked.There are more than 32 million users and the manufacturers involved in the construction are nearly more than 20.The interoperability between different manufacturers and types of equipment is the key problem of system design.How to quickly and accurately positioning the compatibility between equipment becomes the urgent affair.According to the demand,ETC data monitoring and fault location system based on the Costas loop is designed,and the working principle,overall framework and developing thought of the system are described.The system has been developed and widely applied in ETC networking.It has played an irreplaceable role in the fault location,determination,protocol conformance specification for construction.Compared with the existing schemes,the proposed system has improved the sensitivity of 15 dBm and is featured by simultaneously intercepting multiple channel and supporting data concurrency.关键词
